Title: Metallurgical furnace without a regenerative system - where part of the exhaust gas is returned to the hearth with oxygen
Inventor: SCHMITT WILHELM DR ING
IPC: F27B3/22
Filed: 1974-09-19
Abstract: Parent patent describes a process and a device in which an oxygen-nitrogen mixt. is enriched by adding oxygen and the resultant mixt. combined with part of the exhaust gas from a flame-heated metallurgical melting furnace, esp. a steel melting furnace, so that the oxygen is diluted to a concn. similar to that in air prior to the combustion process. In this addition the exhaust gases and the oxidn. gases are mixed in a device which is located outside the hearth region. In the pref. device, part of the exhaust gas is drawn into a duct by blowing oxygen through a jet into the duct and thus creating suction which draws the exhaust gas into the duct. Ensures that an adequate amt. of exhaust gas is recycled through the furnace.

Filed: 1974-10-01
Abstract: The oxidation of p-xylene and p-methyl toluate in a ratio of 1:1-1:3 to p-toluic acid terephthalic acid and terephthalic acid mono- and di-methyl ester, is effected with air at 120-165 degrees C and =10 atmos. press. using catalyst comp sing organic salts of Co, Mn and ni, there being present in the reaction mixture 0.001-0.1, esp. 0.005-0.01% Co, 0.0001-0.05 esp. 0.0001-0.001% Mn and 0.00002-0.01, esp. 0.00002-0.0001% Ni. Increased yields of final products are obtained, i.e. from 80% for a catalyst contg. only organic Co salts and from 83% for a two-component catalyst contg. Co and Mn salts, to >85% for the present three-component catalyst.

Title: Supply circuit for fluorescent lamps - has extra capacitor and PTC resistor to compensate series inductors pause shift and increase life
Inventor: RIEBE WALTER
IPC: H05B41/232
Filed: 1974-10-31
Abstract: The supply circuit, is used to feed fluorescent lamps, and it is designed so that the lamp is coupled in series with an inductor and a diode which is shunted by an NTC resistor. An extra capacitor (7) may be connected between the inductor (3) and the diode and is bridged by a PTC resistor. This capacitor is chosen to compensate for the phase shift introduced by the inductor. (A second fluorescent lamp (13) can be connected over a second inductor (15) to the junction between diode and capacitor). The advantage lies in avoiding cold starting -- thereby increasing the lifetime of the lamp. The diode and NTC resistor are connected between the terminal (1) and the connection for the inductor (15).

One end guide roller for pre-pressing, final pressing, surface finishing. The length of link-plate belt is considerably reduced, for a given size of press, thus reducing the total cost.
Patent DE-2459001-A1 (DE)
Title: Ring surrounding fuel-injection nozzle of jet engine burner - forms auxiliary combustion chamber and stabilises and shortens main flame
Inventor: HENKEL HELMUT
IPC: F23R3/28
Filed: 1974-12-13
Abstract: The ring (2) continues the main body of the nozzle; the air flowing past it is urged towards the burner's axis, making for a more stable, compact flame, and becomes turbulent in the axial region, the better to mix with the fuel; a small amount of air curls round the downstream lip of the ring and burns with a little fuel there; the heat produced pre-heats the main charge, which then burns more quickly and with a shorter flame; this increases efficiency and output power as well as reducing the necessary length of the burner tube.

Title: Detection and signalling of mercury cathode failure - due to cell base exposure in chlor-alkali electrolysis
Inventor: OTTERSKY HERBERT DR
IPC: C25B15/02
Filed: 1974-12-24
Abstract: In a process for detecting and signalling the exposure of cathodic base plate in horizontal Hg-cells for chlor-alkali electrolysis due to locatised discontinuity in the mercury overlay, the electrical voltage (U) between the cathode and >=1 anode, and/or the current (I) of >=1 anode, is measured over a fixed time interval DELTA t. The difference DELTA U and/or DELTA I over time interval DELTA t is compared with a max. increase rate value DELTA U (failure) and/or DELTA I (failure) for the same period of time and a detected failure initiates an alarm, a corrective procedure or cell shutdown. DELTA U (failure) and DELTA I (failure) area measured for the particular cell under deliberately created failure conditions. The procedure has a high degree of reliability.

Title: Sewage sludge dewatering - in pocket filters with gradually reducing volume in predewatering stage before drum filter and plate press
Inventor: BAEHR ALBERT
IPC: B01D33/00
Filed: 1975-06-04
Abstract: Sludge produced in sewage treatment plant is dewatered in a drum filter press preceded by >=1 pre-dewatering appts. and followed by >=1 high-pressure dewatering machine. The continuous flow of sludge is split in one of the pre-dewatering stages into several discrete units. During the dewatering the space taken up by one unit is decreased to suit the volumetric redn. The lengthening of the time available for dewatering results in a high content of solid matter (about 20%) so that the subsequent dewatering stage starts with much more favourable conditions.

Title: Tyre fitting and removal rig - with contoured roller to exert even pressure on tyre walls carried by turntable
Inventor: GOEBEL EICKHART
IPC: B60C25/132

Title: Mechanical regenerative braking for go-kart - with flywheel on rigid drive axle and selective clutches coupled via chain drive
Inventor: EMMER RUDOLF-JAKOB
IPC: B60K6/10
Filed: 1975-11-25
Abstract: The rigid drive axle (1) of the go-kart is fitted with a flywheel (10) rotating on the shaft on bearings so that energy can be stored independent of the shaft. Two sets of clutches (11, 5, 6) are fitted to selectively couple the flywheel to the axle for energy transfer. Energy is stored during braking, as a regenerative process, and tapped off during acceleration. During braking one clutch (5, 6) couples the drive shaft to the flywheel via a chain driven gearing (7, 8) so that the flywheel is spun faster than the axle. During acceleration a second clutch (11) couples the axle directly to the flywheel. The system improves the performance of the vehicle and saves brake wear.

Abstract: 1523047 Cation exchange membranes for brine electrolysis cells ASAHI KASEI KOGYO KK 2 July 1976 [9 July 1975(2) 31 March 1976] 27654/76 Heading C7B [Also in Divisions B5 and C3] Electrolytic cells, especially for brine, have the anode and cathode compartments separated by a cation exchange membrane comprising a fluorocarbon polymer containing pendant carboxylic groups of formula -OCF2COOM, where M is hydrogen, ammonium, quaternary ammonium or metal. The said groups are obtained by reduction of -OCF 2 CF 2 SO 3 X groups (see Division C3), and the membrane may contain residual groups of this type. Preferred membranes contain -OCF 2 COOM groups on one surface, which faces the cathode, and -OCF 2 CF 2 SO 3 M groups on the opposite surface. The membrane may be formed from a single film, or may be a composite of two polymeric films, and in either case it may further include a reinforcing layer, e.g. a fabric formed from PTFE fibres. The 27 specific examples describe a variety of such membranes and their application in the electrolysis of brine, the starting copolymers being of tetrafluoroethylene and perfluoro (3, 6-dioxa- 4-methyl-7-octene sulphonyl fluoride, in some cases with a further monomer which is hexafluoropropene, perfluoropropyl vinyl ether or perfluoro- 3, 6-dioxa-5-methyl-nonene-1.
